- although I do not confine myself to this specific use but reserve the right to apply it to any purpose for which it is adapted.

The invention consists in the novel construction, combination and arrangement of parts hereinafter described, pointed out in the claims, and illustrated in the accompanying drawing, in which Figure 1 represents a front elevation of the carbureter. Fig. 2 shows aside elevation of the same. Fig. 3 is a vertical central section on line IIIIII of Fig. 2. Fig. 4 is a broken vertical section on line IVIV of Fig. 1.

In carrying out the invention I employ a 2 for the admission of air and provided wit a flange 3 at its discharge end, whereby it may be readily secured to the gas-engine (not shown.)

4 designates a disk-va ve arranged in the discharge end of the casing upon a shaft 5, projecting through'one end of said casing, and rovided with a crank 6 adjustablysecured thereto by a set-screw 7.

8 designates a circular spreader centrallylarged portion of the casing. Said spreader has a concaved upper surface 10 for retaining the hydrocarbonoil as it drops thereon until saidoil' evaporates. Said spreader is hollow and connected'to the lower ortion of the casing by a tubular stem 11 t rough which a pipe.12 extends, said pipe being, preferably, connected with the exhaust pipe of the engine, so that heat may be introduced into the chambered spreader and thus hasten the process of va orlzin the oil as it drops upon said sprea er. T e vaporization of the oil is further hastened by the introduction of air. through 0 ening 2 and directed against the spreader y an inverted frustoconical flange 13 integral with the casing."

14 designates an Oll supply pipe secured commumcating I Specification of Letters Patent. Application filed February 7. 1907 Serial H0. 356.204.

'with a vertical chamber 15, provided at its up er portion with a stuffing-box 16 and at its ower tapered end with a nozzle 17 having a valve-seat 18 centrally-disposed above the spreader8.

19 designates a needle-valve extending through chamber 15 for controlling the flow of oil. The upper threaded end'20 of the needle-valve is adjustably "engaged by a nut I 21 to which a lever' 22 is pivotally secured by screws 23, Said nut is reliably locked in position by a clam ing-nut 24. Lever 22 is fulcrumed upon t e upper end of an arm 22 projecting from chamber 15.

25 designates a bell-crank lever connected to lever 22 by a link 26. Each of said levers has a series of holes 27 28 for the adjustable reception of link 26 and whereby the movement of the needle-valve is adjusted, for instance, by placing the ends of the link throu h the holes nearest the fulcrumed oints of t e levers, it is obvious that the nee e-va'lve will be raised but ashort distance above its seat and permit but a small amount ofgasolene to the nozzle. Valve 4 is simultaneously 0 ened with :the' needle-valve to permit the mixture to be drawn into the en e by a link 29 pivotally secured at its em? has an eye 30 for the reception of aconnecting-rod or other device employed in actuatmg the lever. By employing; the above connections it is obvious that the strokes of the needle-valve may be varied to admit more or less oil without checking the action of valve 4 which is always opened to the widest point so that the mixture will have free ingress to the cylinder.

31 designates a drain leadin from the discharge end 3, for the escape o any oil which may accumulate therein.

From the above description it is obvious that .I have produced a carbureter which is of simple and com act construction, and thoroughly adapted or the purpose intended. Havmg thus described my invention, what I claim is A carbureter consisting of a mixin -chamher, an oil inlet pipe openin into sai chams to crank 6 and oneend of lever 25. The upper arm of lever 25-;
